A restaurant's processing rate should be read from the statement, not from the headline rate on a POS quote. Divide all processing fees by card volume, then separate card-network interchange and assessments from processor markup, monthly charges, downgrades, and other line items. Tips, card-present volume, rewards cards, and online orders change the underlying mix.
Restaurant owners often compare one blended number with another owner's number even though the two businesses accept different cards through different channels. A counter-service debit mix does not carry the same interchange as corporate cards, rewards cards, keyed catering invoices, and online orders. The fair comparison is the controllable markup above the documented network cost for the actual mix.
What the record changes
Use a full month with normal volume. Include every processing charge, statement charge, software-linked fee that is actually a processing fee, and any credit or adjustment. The audit should explain where each dollar landed, identify lines it could not classify, and state the public Visa or Mastercard schedule and effective date used for the reconstruction.
- Restaurant owners in the research record ask what peers pay for Square and Toast, with one Toast discussion drawing 140 comments.
- Visa and Mastercard publish interchange schedules, which lets a statement audit distinguish network cost from the amount retained elsewhere.
- This report names no processor and accepts no processor money, so the owner can use it to evaluate the current statement rather than receive a disguised switching pitch.
How to use this answer
A useful statement review starts with one equation: total processing fees divided by total card volume. The full audit then reconstructs that total from interchange, network assessments, processor markup, and other fee lines. The components must add back to the statement total within tolerance before any markup or unexplained fee is described.
- Use the statement's total card volume and total fees to calculate the effective rate before comparing any quoted percentage.
- Separate public network costs from the processor's markup and classify every monthly, batch, downgrade, PCI, or other fee line.
- Reconcile the components to the statement total, then send the owner-written request for specific fee removals or a specific markup.
